Gas REGULATOR.

Application filed December 10, 1921. Serial No. 521,558.

To all whomc't may concern Be it known that I, JAMES J. SoHEURIoH, a citizen of the United States, residing at Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Gas Regulators, of which thefollowing is a specification, reference being had to the accompanying drawmgs. i j I j I This invention relates to pressure ratus, particularly to regulators, for its object the provision of a novel device which will automatically regulate the pressure or flow of to a low pressure for use wherever desired, the device being intended primarily for use in flour mills for regulating the pressureot chlorine-gas, though no restriction as to its use is intended for the reason that it is well adapted to be employed in a wide variety of arts and for a multiplicity of purposes. v

An important object is vtheprovision of a gasregulator of this character which is read ily adjustable whereby to control the pressure or flow and maintain it at a uniform degree, the adjusting means being furthermore so constructed and arranged as to be readily accessible Without disassembling the device.

Another and more speciiic object is the provision of a regulator for this purpose which embodies a' flexible diaphragm having operative connection with a control valve, means being provided for applying phragm for the purpose of :varying its sensitiveness andopposing the action of the gas under pressure.

An additional object is the provision of a device of this character which will be simple stall, automatic in operation, positive in action, durable in service and a general improvement in the art, I

With the above and other objects andadvantages in view, the invention consists in the details of construction tobe hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which: c

and has 7 gas and reduce it from a high a r pressure against oneside of the dia-c fbers 30 and .of this diaphragm is a threaded stub 33 which against the other side thereof. and inexpens ve'ln manufacture, easy to m- Referring more "particularly to the draw lng s, I have shown my device as comprising a circular casing which in actual practice is formed of two sections 10 and 11, formed with outwardly extending flanges 12 and 13, respectively, bolts 14. The section 11 is formed with an inwardly extending flange ll fto which is secured, as by means of bolts 15, an outwardly extending flange 16 formed on a cover 17.

Formed within the'section 11 and extend? ing diametrically thereacross is a bar 18 which is formed with a longitudinally extending channel 19 which extends through one side of the section 11 and'which constitutes the high pressure feed to the device. Leading into the outer end of this channel is a split pipe 20 leading from any suitable source of gas under more or less high pressure and associated with this pipe 20 is a conventional pressure gauge 21. At its center the bar 18 is formedwith a small lateral passa e 22 which leads intoa threaded recess 23 within which is screwed a plug 2 1 having a bore 25 registering with thefpassage 22 and terminatingat its outer, endin a valve seat. Leading through the cover 17 is a pipe 26 which leads to a conventional pressure gauge 27 and with which is connected a pipe 28 for conducting thegas to the place where it is to be used.

Secured between the flanges 12 and 13 is a flexible diaphragm 29 which divides the interior of the entire casing into two chain 31. Disposed against one side plate 32 carrying a passes through the. a plate 34 disposed Engaged upon thestub 33 is a nut 35 which holds the plates 32 and 3 1 properly clamped upon the diaphragm. Carried by the plate 32 are spaced parallel posts 36 which are disposed at opposite sides of the bar 18 and which have threaded ends 37 which are passed freely through a cross bar 38 through the center of which is screwed a valve 39 terminating in a conical point 39 cooperating with the valve seat formed at the end of the bore 25. The bar 38 is held in adjusted. position upon the posts 36 by means of twanuts 40 threaded upon each post and engaging against opposite sides of the bar. The valve 39 is itself adjustable and has its upper end formed with a slot within which diaphragm and through secured together as by means of may be engaged a screw driver or the like for effecting adjustment and the cover 17 is formed centrally with a threaded hole 41 in which is screwed a plug 42 which is removable to permit access to the valve, a screw driver or the like being insertable through this hole 41.

Leading into the casing section 10, that is into the chamber 30, is a pipe 43 leading from any suitable source of compressed a1r and associated with this pipe is a conventional gauge 44.

Assuming that the device has been constructed and assembled as above described, the operation is as follows: The gas under high pressure is introduced through the pipe 20 and will pass through the channel 19, passage 22 and bore 25 into the cham ber 31. Any desired degree of pressure is applied to the chamber 30 through the compressed air conducting pipe 43. The gas Within the chamber 31 of course passes out through the pipe 28 to wherever it is to be used. When the gas within the chamber 31 exerts a certain predetermined pressure governed by the adjustment of the parts, the diaphragm 29 will bow against the resistance of the pressure within the chamber 30 and this will result in movement of the posts 36 carrying the cross bar 38 which in turn carries the valve 39 and the valve will then seat and close the outer end of the bore 25 and consequently cut off the inlet of high pressure chamber 31 is reduced to the proper degree. This action is entirely automatic and will result in producing a gas flow through the pipe 28 of absolutely uniform pressure. The sensitiveness of the device is readily regulatable by adjusting the valve 39 and by varying the pressure within the chamber 30 so as to meet any and all conditions which may arise.

From the foregoing description and a study of the drawings it will'be apparent that I have thus provided a simply con structed and consequently inexpensive pressure regulator which will be entirely automatic in action and which will require no attention after the parts have once been set or adjusted to result in the proper flow. It is to be noted that while the device is de scribed as being for regulating gas pressure it might also be used for regulating the pressure of a current of liquid, and in the event that chlorine in the art specified, it is advisable that the parts exposed to the action of the gas be constructed of bronze or other suitable non-corrosive material. It is also to be observed that the plug containing the valve seat may be removed in case of wearing out of the valve seat so that the device may be made as good as new even after long use. Owing to the simplicity of the con- 7 parts as will not gas until the pressure within the the device is used for handling struction and the fewness of the parts, it is apparent that there is practically nothing to get out of order and that the device should consequently have a long life and satisfactorily perform all the functions for which itis intended.

While I have shown and described the preferred embodiment of the invention it is, of course, to be readily understood that I reserve the right to make such changes in the form, construction and arrangement of depart from the spirit of the invention or the scope of the subjoined claims.
